PHOTOG RAPHlC-PRINT FABRIC.

SPECIFICATION forming part of Letters Patent No. 645,952, dated March2'7, 1900.

Application filed April 2, 1898. fierial No. 676,231. (No model.)

To all whom it may concern:

Be it known that Lluans ARTHUR HARVEY, of the city of Toronto, in thecounty of York and Province of Ontario, Canada, have invented certainnew and useful Improvements in Photographic-Printing Materials, of whichthe following is a specification.

My invention relates to an improved fabric material to be sensitized andon which a shadow is cast by exposure-to the light which passes througha transparent drawing,tracing, negative plate, film, or other object andforms a print of whatever is desired to be printed and which is fullydevelopedby a subsequent bath.

The objects of the said invention are, first, to produce aphotographic-print fabric possessing greater strength and durabilitythan paper or other material or materials heretofore in use, whether ofthe negative or positive, and of blue, black, or other colors; second, aphotographic material that does not stretch or alter its dimensionsduring the bathing or development thereof, thereby preserving thecorrect scale, size, or dimension of the drawing or object producedthereon; third, a photographic-ground material that does not partake ofpermanent set or a tendency to roll up when opened out after having beenkept rolled some time, and, fourth, a photographic-print fabric that isunaffected by Wet or moisture.

In the accompanying drawing, intended to illustrate my invention, thesingle figure showsarectangularpiecehaving the portionA to designate thesensitized face or surface, B to designate the fabric or meshed surfacebefore being sensitized, and O to represent the rightend portion, therubber backing having the fabric removed from the front of it andexhibiting the meshed surface similar to but darker than the fabric.

My invention consists in applying a water= proof backing O or surface toawoven fabric B, of fine and uniform mesh or texture, so as not todestroy the absorbent quality of the unfaced surface of the fabric bypassing through or fully permeating the said fabric, and therebypreventing the surface receiving the usual sensitizing solution. Thefabric B may be linen, cotton, silk, fine Woolen, or other fiber, andthe backing 0, applied thereto, is essentially pliable and waterproofand may be either rubber or a composition of non-drying oil, white lead,and other substances to form a pliable pigment when applied to thefabric. The opposite side of the fabric from that coated as described issensitized, similarly as paper is prepared, with bromid, nitrate, orferricyanid solutions, and on these I make no claim of novelty, beingwell known in photography.

Having described my invention, what I claim, and desire to secure byLetters Patent, 1s

As a new article of manufacture, a photograph-print fabric composed of awoven fab ric of fine and uniform texture having one surface or sidethereof coated with a pliable waterproof material or composition, andthe opposite or reverse surface sensitized with a photographic solution,substantially as and for the purpose set forth.
